Answer:

[tex]S_{10}[/tex] = - 30

Step-by-step explanation:

For a given arithmetic sequence the n th term formula is

[tex]t_{n}[/tex] = [tex]t_{1}[/tex] + (n - 1)d

where d is the common difference and [tex]t_{1}[/tex] the first term

We have to find d and [tex]t_{1}[/tex]

from the given information we can write 2 equations and solve for d and [tex]t_{1}[/tex]

[tex]t_{6}[/tex] = [tex]t_{1}[/tex] + 5d = - 4 → (1)

[tex]t_{10}[/tex] = [tex]t_{1}[/tex] + 9d = - 12 → (2)

subtract (1) from (2) term by term

4d = - 8 ⇒ d = - 2

substitute d = - 2 in (1)

[tex]t_{1}[/tex] - 10 = - 4 ⇒ [tex]t_{1}[/tex] = - 4 + 10 = 6

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][2[tex]t_{1}[/tex] + (n - 1)d ], hence

[tex]S_{10}[/tex] = 5[(2 × 6) + (9 × - 2) ] = 5(12 - 18) = 5 × - 6 = - 30

Answer:

It's B.

Step-by-step explanation:

(x, y) ---> (x + 3, y - 1)

Using point X as an example:

(x, y) ---> (x + 3, y - 1)

(0, 0) ---> (0 + 3, 0 -1)

(0, 0) ---> (3, -1)

The algebraic rule that describes the transformations is;

B) (x, y) → (x + 3, y − 1)

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given, A graph where we can see a Graph of a triangle XYZ that transforms to become x'y'z'.

Since the given graph is transformed not scaled.

Thus, the dimension will be the same and we can justify the means by just Calculating for one point.

For Point x:

Original coordinates os x = (0, 0)

coordinates of the x after transformation = (3, -1)

Thus,

horizontal displacement in X = +3

vertical displacement in X = -1

therefore, (x, y) → (x + 3, y − 1) is the algebraic rule that describes the transformation.

Answer:

4

Step-by-step explanation:

Choice C for problem 6 is correct. The two angles (65 and 25) add to 90 degrees, proving they are complementary angles.

===========================================

The answer to problem 7 is also choice C and here's why

To find the midpoint, we add up the x coordinates and divide by 2. The two points A(-5,3) and B(3,3) have x coordinates of -5 and 3 respectively. They add to -5+3 = -2 which cuts in half to get -1. This means C has to be the answer as it's the only choice with x = -1 as an x coordinate.

Let's keep going to find the y coordinate of the midpoint. The points A(-5,3) and B(3,3) have y coordinates of y = 3 and y = 3, they add to 3+3 = 6 which cuts in half to get 3. The midpoint has the same y coordinate as the other two points

So that is why the midpoint is (-1,3)

Answer:

x=3, y=6

Step-by-step explanation:

4x-y =6

3x+2y = 21

To use elimination we will multiply the first equation by 2

2(4x-y) =6*2

8x -2y =12

We will add this equation to the second equation to eliminate y

8x -2y =12

3x+2y = 21

-----------------

11x = 33

Divide each side by 11

11x/11 = 33/11

x =3

We still need to solve for y

3x+2y = 21

Substituting x=3

3*3+2y = 21

9+2y =21

Subtract 9 from each side

9-9+2y = 21-9

2y = 12

2y/2 = 12/2

y =6

Step-by-step explanation:

Answer: lower right hand corner

In this corner is an expression that has "pi" in it that doesn't cancel out like it does in the upper left hand corner. The number pi is irrational because it cannot be written as a fraction of two whole numbers. We can sorta get close when we say 22/7 = 3.14129 but the more accurate version of pi is pi = 3.14159; however we cannot get an exact match.

Discussion:

Let's determine the pattern.

first term:  -3

2nd term:  (-3) * (-6) = 18                     (multiply first term by -6)

3rd  term:  (18) * (-6) = -108                 (multiply 2nd term by -6)

6th term :  (-3888)*(-6) = 23328         (etc)

7th term:   (23328)*(-6) =  -139967     (etc)

Sum = -119,962

A simpler way to do this is to use the formula for the sum of a geometric series to n terms. The series is

Distance d= 15

Gallons of gas (g)= 1/2

Equation is d= rg

15 = r* 1/2

Now we divide by 1/2 on both sides

[tex]r=\frac{15}{\frac{1}{2}}=15 * \frac{2}{1}= 30[/tex]

Answer: its D $721.50

Answer:

50 dollars

Step-by-step explanation:

If you have a 20% discount,that means you pay for 80% of your items. So to find percent you make 80 percent 0.8 and then multiply by 62.50.

Answer:

$10

Step-by-step explanation:

You would multiply $62.50 by 20% or .2 to find the discount which is $10. If you need to find the sale price you would subtract $62.50 - $10 = $52.50.

Your discount amount is $10

Answer:

y=  5x + 3

Step-by-step explanation:

This is because you solve for slope, which is 5, then plug that into point slope form to get:

y - 8 = 5(x - 1)

y - 8 = 5x - 5

y = 5x  + 3.

Answer:

y = 5x + 3

Step-by-step explanation:

Step 1. Find the slope

Each time x increases by 1 unit, y increases by 5 units.

m = slope = 5/1 = 5

Step 2. Find the y-intercept.

y = mx + b

When x = 4, y = 23.

23 = 5×4 + b

23 = 20 +b

 b = 3

y = 5x + 3

The graph is a straight line with slope m = 5 and a y-intercept at y = 3.

[tex]m\angle M=90[/tex]

[tex]m\angle A=63[/tex]

[tex]m\angle N=27[/tex]

[tex]\Delta MAN[/tex] is a right triangle.

Step-by-step explanation:

Since we know that sum of all angles of triangles equals to 180 degrees.

To find the measure of our given angles we will have to find the value of x. The value of x can be found by equating the measure of all angles of our given triangle with 180.

[tex]4x-5+9x-9+10x+10=180[/tex]  

[tex]23x-14+10=180[/tex]  

[tex]23x-4=180[/tex]  

[tex]23x=180+4[/tex]

[tex]23x=184[/tex]  

[tex]x=\frac{184}{23}[/tex]

[tex]x=8[/tex]    

Now let us find measure of each angle by substituting value of x in given expressions.

[tex]m\angle M=10*x+10[/tex]

[tex]m\angle M=10*8+10[/tex]

[tex]m\angle M=80+10[/tex]

[tex]m\angle M=90[/tex]

Therefore, measure of angle M is 90 degrees.

[tex]m\angle A=9*x-9[/tex]

[tex]m\angle A=9*8-9[/tex]

[tex]m\angle A=72-9[/tex]

[tex]m\angle A=63[/tex]

Therefore, measure of angle A is 63 degrees.

[tex]m\angle N=4*x-5[/tex]

[tex]m\angle N=4*8-5[/tex]

[tex]m\angle N=32-5[/tex]

[tex]m\angle N=27[/tex]

Therefore, measure of angle N is 27 degrees.

From the measures of angles we can say that triangle MAN is a right triangle.

Answer:

t=3

Step-by-step explanation:

Simplifying

5 + -1(t + 3) = -1 + 2(t + -3)   Reorder the terms:

5 + -1(3 + t) = -1 + 2(t + -3)

5 + (3 * -1 + t * -1) = -1 + 2(t + -3)

5 + (-3 + -1t) = -1 + 2(t + -3)

Combine like terms: 5 + -3 = 2

2 + -1t = -1 + 2(t + -3)

Reorder the terms:

2 + -1t = -1 + 2(-3 + t)

2 + -1t = -1 + (-3 * 2 + t * 2)

2 + -1t = -1 + (-6 + 2t)

Combine like terms: -1 + -6 = -7

2 + -1t = -7 + 2t

Solving

2 + -1t = -7 + 2t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-2t' to each side of the equation.

2 + -1t + -2t = -7 + 2t + -2t

Combine like terms: -1t + -2t = -3t

2 + -3t = -7 + 2t + -2t

Combine like terms: 2t + -2t = 0

2 + -3t = -7 + 0

2 + -3t = -7

Add '-2' to each side of the equation.

2 + -2 + -3t = -7 + -2

Combine like terms: 2 + -2 = 0

0 + -3t = -7 + -2

-3t = -7 + -2

Combine like terms: -7 + -2 = -9

-3t = -9

Divide each side by '-3'.

t = 3

Simplifying

t = 3

Answer: vertical asymptotes: x = 2, x = -2

              horizontal asyptote: y = 3

Step-by-step explanation:

[tex]\dfrac{3x^2}{x^2-4}[/tex]

Vertical Asymptotes are the restrictions on "x", which is denoted by the denominator being unequal to zero.

x² - 4 = 0

(x + 2)(x - 2) = 0

x + 2 = 0      and       x - 2 = 0

     x = -2     and             x = -2

Horizontal Asymptotes are determined by the degree of the numerator (n) compared to the degree of the denominator (m) as follows:

In the given problem, the degree of both the numerator and denominator is 2 so horizontal asymptote is: [tex]y = \dfrac{3}{1} = 3[/tex]

She will need 8 scoops for the recipe if the baker has 2 2/3 cups of flour for her recipe, but she only has a 1/3 cup scoop.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

A baker has 2 2/3 cups of flour for her recipe

2 2/3 = 8/3

She only has a 1/3 cup scoop.

Scoops she will need for the recipe = (8/3)/(1/3) = 8

Thus, she will need 8 scoops for the recipe if the baker has 2 2/3 cups of flour for her recipe, but she only has a 1/3 cup scoop.
